     * arg of the onInfo() callback: bit 31-28 contains the track id; and

     * the rest of the 28 bits contains the informational event defined here.

     * For example, ext1 = (1 << 28 | MEDIA_RECORDER_TRACK_INFO_TYPE) if the

     * track id is 1 for informational event MEDIA_RECORDER_TRACK_INFO_TYPE;

     * while ext1 = (0 << 28 | MEDIA_RECORDER_TRACK_INFO_TYPE) if the track

     * id is 0 for informational event MEDIA_RECORDER_TRACK_INFO_TYPE. The

     * application should extract the track id and the type of informational

     * event from ext1, accordingly.

     *

     * FIXME:

     * Please update the comment for onInfo also when these

     * events are unhidden so that application knows how to extract the track

     * id and the informational event type from onInfo callback.
